Power management has always been the industry's concern and the key to enhancing user experience in wearable tiny devices. The functions that wearable gadgets can do are gradually being expanded, and the device system's energy consumption has been greatly reduced. The usage of high-efficiency PMICs can enhance power conversion efficiency, lower system power consumption, increase performance per watt, and lengthen the device's battery life. ability.

Low-Power PMICs from Qorvo for Medical Wearables

When it comes to PMICs that may be worn, Some folks may be astonished when it comes to Qorvo. Qorvo is a firm that specializes in supplying wireless RF solutions and is a leader in the sectors of communication base stations, mobile phone RF chips, and Internet of Things RF chips, according to many individuals. Sheep, when did Qorvo first enter the PMIC market? In reality, Qorvo purchased Active-Semi in 2019, a company that specializes in the design and development of power management and motor driver circuits.

In the field of PMIC, Active-Semi has a plethora of experience and technology. Many manufacturers have recognized Active-PMIC, Semi's which has captured about half of the market share in the sports camera area. The market demand for PMICs that may be used in tiny devices is exceptionally high now that the wearable device industry is gaining traction. Qorvo has released the PMIC ACT81460 for wearable devices, based on Active-unique Semi's advantages in the PMIC industry.

Qorvo released the ACT81460 PMIC for compact battery-powered devices. With a quiescent current of 6A, the chip combines a linear charging mechanism. The extremely low standby current helps extend battery life, particularly when utilized in a long-term standby mode. or low-power gadgets Qorvo created a low-power operating mode for battery-powered gadgets to extend their durability even further. The ACT81460 can customize the number of voltage regulators to be switched on or off according to actual demands in low-power mode, resulting in battery optimization. Increase your energy efficiency.

Maxim allows for numerous outputs and 50% smaller PMICs.

Maxim has a variety of wearable devices on the market, including the max20310, a PMIC with ultra-low quiescent current introduced by the company. Two single inductors, two low dropout regulators, and various power management components make up the chip.

The max20310 uses a novel single-inductor multi-output architecture to deliver two programmable voltage output channels with a single inductor, reducing chip space and increasing end-product design freedom. Additionally, the quiescent current of each output may be lowered to a minimum with this design. In the standby mode, the quiescent current is lowered by more than 40% compared to the standard discrete architecture.
